To all whom it may concern:

Be it known that we, HARRY D. HAMILTON and CHAR Es B. Tnznnrrrs, citizens of the -United States, residing in Winthrop, in the county of Suffolk-and Commonwealth of Massachusetts, and Walpole, in the county of Norfolk and Commonwealth of Massachusetts, respectively, have invented certain Improvements in Dispensing Apparatus, of which the following description, in connection with the accompanying drawings,

is a specification, like reference characters on,

workers and shoe repair men in dispensing cement for their operations involves, as far as we are aware, the use of containers which have movable elements liable to become stuck by the accumulation of dried cement, which expose the contents not in use to rapid evaporation and consequent deterioration,

which allow the brush or other applying device to become hardened and deformed, and which are difficult of access in obta1n- 3o ingthe contents or to keep, clean. I Objects ofour invention are to overcome all these difiiculties by the provision of a simple and inexpensive dispensing apparatus, which insures the free supply of the entire ,body of fluid being dispensed, with but slight ex-. posure to evaporatioinand wh ch permits the applying brush to be maintained flexible and in its natural form, and the fluid cone i I place w1th direct rectilinear movement, seals In the attainment of these ob]ects, we

tainer to be easily cleaned. I 40 furnish, as a feature of the invention, a novel container and a cover therefor, the latter having a tubular portion within the container. This tubular portion preferably extends into proximity with the bottom of the container, entering the fluid therein to give a relatively small exposed area intowhich the applying device may be dipped,

the remainder of the surface being shielded against evaporation by means of a pref era-bly hermetical closure at the 1uncture of the container and cover. The tubulardelivery portion is shown as passing outside.-

sure which serves to support the applying device. This. closure protects the surface of the fluid within the tubular portion, into which the applying device dips, against evaporation when said applying device is not in use, and by having frictional engagement between the closure and applying device, the latter may be adjusted vertically to establish and maintain correct relation between it, the surface of the fluid and the end of the tubularportion. One of the many embodiments of the invention is hereinafter more particularly described and claimed, reference being had to the accompanying drawing, in which- Fig. 1 illustrates in broken perspective one form of our improved container;

Fig. 2 is a side elevation, with the container in section,;showing the step of assembling the dispensing cover with the coutainer to establish the barometric feed;

Fig. 3 is a broken perspective of the container, having assembled with it the delivery and. applying devices and Fig. 4 shows in broken side elevation the delivery device employed for protecting the applying device.

The numeral 10 designates apail, or other suitable container,'which may be constructed of sheet metal. The container is preferably ofconsiderable diameter as compared with its height. The top of the container has anopeningl l of a diameter approaching that of said container, it being here shown asarranged for engagement at its inner edge by the well-known friction type of cover,'i1lustrated at 16 in Fig. 1 of the drawing, This cover, when forced into of the cover, this being, in the present in stance, by its frictional engagement. Opening through the center of the cover 18 is a delivery tube having a portion 20 depending from the cover, and reaching a plane in proximity to the bottom of the'container 10. The diameter of the portion 20 is substantially less than that of the container,

tact with the upper edge of the portion 24' is a closure 26, in the form of a circular disk of preferably flexible material, asrub-' her. At the center of this closure is an opening 28 to engage, with some frictional resistance againstmovementthrough it, the" handle 30 of such an applying device as a brush 32.

The containers may be of such a capacity that they will hold some quantity of cement convenient for use by an operative, say, one or two quarts. lVhen prepared for sale,- they may be closed either by a storage cover 16 or the dispensing cover 18. arrangement is better suited for factory use, since one of the dispensing covers may be utilized with a plurality of the containers held sealed by the cover 16 in storage. Forshoe repair men it may be convenient to market the container with the dispensingcover, thereafter containers with the storage cover being purchased and the dispensing cover obtained with the first container used therewith. When the container is put out closed by the cover 18, the portion 24 of the dispensing tube may be covered by a soft metal seal, or may have inserted in it a stopper, the inclination being such as to facilitate this. Assuming that the apparatus is being employed in a shoe factory, an

operative, upon beginning work, will receive from the stock room a container closed by its storage cover, and will then remove this and substitute the dispensing cover. The upper end of the delivery tube, while the lower portion 20 is being inserted in the contents of the container, maybe sealed by the palm ofthe hand, as illustrated, in Fig. 2 ofthe drawings, or may be closed by the a disk 24 carrying the brush. In the latter case, the efli'cacy of the closure is increased by having a ring of cement upon the upper edge of the tube portion'24. With the outer end of the delivery tube closed in either manner, it and the contained body of'air displace a portion of the cement upwardly between the portion 20and the cylindrical wall of the container, and before breaking the closure at the top ofthe'tube', the outer edge of the cover 18 is pressed intoenga'ge5 ment with the'top 12 of the container to form a seal along this line. closure being air-tight, there will'be held The former The latter by'atmospheric pressure an elevated body of cement in the-annular space about the delivery tube, but a small quantity rising into the lower end of the tube. The handle of the brush 32 may then be adjusted through the closure 26 until the bristles dip to the desired extent in the cement within the tube, when the closure rests upon the tube portion 24. The apparatus is now ready for use. YVheIi-the operator withdraws the brush to apply the cement held by its fibers to the work, the inward inclination of the tube portion 22-tends by its contact to straighten the fibers" and to remove the excess of cement therefrom. Cement received upon this portion 22 news down it to the tube portion 20, and is returned to the body within the container, being prevented from dripping upon any portionof the brush, as might be the case were this contracted section of the tube parallel to the cylindrical portion, instead of inclined; When the charge upon the brush has been applied and it is to be returned to the container for a fresh supply, the downward and inward inclination of the portion 24 of the tube facilitates its introduction without disturbing the normal parallelrelation of the fibers, and drops of cement falling upon this wall 24 are conducted over the lower tube sections to the supply in the container without coming into contact with the brush. After the entire elevated portion of the contents of the 0011- tainer has been used and the level of the cement inside and outside the tubular portion 20 is the same, the brush handle may be lowered through its supporting disk to permit the operator to use the entire contents. It'is to be observed that prior to this lowering" of the fluid level, the entire body of cement between the tube and'container walls isprotected against evaporation, there onl being exposed to the air'asurface of limited area within the tube.

At the close of his work, the operative removes the dispensing cover 18 and sets it upon the bench, or other suitable surface, the lower edge 'of'the portion 20 co1ning in contact with this support. The brush at this time should be so positioned in the closure 26' that the lower extremities of its fibers are above the bottom edge of the tube. When thus disposed, the applying portion of the brush, it will be seen, is entirely enclosed, laterally by the delivery tube, at

the top by the closure 26 and the brush handle, and at the bottom by the supporting surface. Th-is,while not entirely air-tight, gives little opportunity for evaporation, and

the drip from the tube tends to increase the perfection of the enclosure. Moreover, if, when'the brush is thus arranged, it carries in its fibers some of the cement, this, drippingupon the supporting surface, will flow to the edges of the tube, aiding in effecting a seal. There is also usually a certain amount of cement upon the under side of the closure 26 which will more effectively seal the line of contact between this and the upper extremity of the delivery tube. The container is sealed by the replacement of the storage cover 16 and is returned to the stock room, or it may be cleaned out and refilled with fresh. cement and then sealed. In doing this, it will be obvious that, since the diameter of the opening in the top of the container is nearly as great as that of the container itself, any cement which has accumulated upon the sides or bottom of the container may be readily removed by the insertion of the hand. When the operative resumes work, he may be provided with the refilled container, or a fresh one, and utilizes the contents in the same manner as already described.
